How do you keep up with the standards, packet formats, state machines, etc to do your job?

I have huge problems keeping, in my head, all the information I need to do my job. On a single day I might work with container networking interfaces, TCP packets, OVS flow tables, firewall configurations, BGP routing tables. I spend a lot of my time debugging wire problems like TCP state machines that aren't behaving the way they should, packet formats (spent all day on VXLAN debugging yesterday) and generally doing research into things that are new or changing. I have notes but I keep having to relearn stuff I learnt. How do you guys deal with this information overload?
